An Andersen 400 Series slider window typically costs about $450-$1,500 for the unit, with installed prices commonly ranging from $800 to $2,600 per window. Size, glass package, frame color, replacement conditions, and local labor rates account for much of the difference; large or custom configurations can cost more.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Window unit | $450 | $850 | $1,500 | Standard sizes and common glass options |
| Installed replacement | $800 | $1,450 | $2,600 | Per window; assumes ordinary access |
| Large or upgraded unit installed | $1,400 | $2,300 | $3,800 | Oversized dimensions, premium glass, or difficult opening |
| Multi-window project | $3,200 | $7,250 | $13,000 | Four to eight windows, before unusual repairs |
Assumptions: U.S. pricing for common residential sizes, standard installation, and no major structural repair. Local quotes vary.
What Andersen 400 Series Slider Windows Usually Cost
The 400 Series gliding window is a wood-interior, vinyl-clad product with one or more sliding sash configurations. A common-size unit may cost about $450-$1,000 before installation; larger units, specialty dimensions, upgraded glass, or custom exterior colors can push the product price toward $1,500 or higher.
For a straightforward replacement, homeowners often pay approximately $800-$1,800 per opening, including the window, removal of the old unit, installation, insulation, and basic trim work. A full-frame replacement that exposes or repairs the rough opening may reach $1,400-$2,600 per window. For ordinary projects, budgeting about $1,200-$1,800 per installed window is a workable starting point.
Prices depend on the exact configuration, not just the series name. A quote should identify the unit dimensions, operating-panel layout, glass type, grille selection, interior finish, exterior color, and installation method. Confirm whether sales tax, delivery, disposal, and interior or exterior trim are included before comparing bids.
How Glass, Frame, and Installation Shape the Quote
Window pricing divides between the manufactured unit and the work needed to fit it into the home. The following ranges are planning estimates, not a fixed Andersen price list; dealer discounts, product availability, and project scope affect actual quotes.
| Quote component | Typical price | Pricing basis | What it covers | Common cost trigger |
|---|---|---|---|---|
| Window unit | $450-$1,500 | Per window | Frame, sash, standard hardware, selected glass | Large size or specialty options |
| Installation labor | $250-$700 | Per opening | Set, shim, fasten, insulate, and seal | Full-frame work or tight access |
| Removal and disposal | $50-$175 | Per window | Old unit removal and ordinary disposal | Heavy or damaged frames |
| Trim and finish materials | $75-$350 | Per opening | Flashing, sealant, casing, and minor finish items | Nonstandard trim or exterior repair |
| Opening repair | $150-$1,000+ | Per opening | Localized framing or water-damage correction | Rot, mold, or altered framing |
Labor charges for a simple opening may work out to roughly $75-$125 per crew hour, though contractors usually quote the job rather than bill by the hour. The unit may be only part of the total: trim, water management, access, and repair work can materially change the installed price. Ask the contractor to separate the window, installation, removal, and repair allowances.
Which Window Sizes and Glass Options Raise the Price?
Dimensions are among the clearest price drivers. A standard opening around 36 by 24 inches may fall near the lower end of the product range, while a 60-by-48-inch unit typically costs more because it uses more glass and requires heavier sash components. Openings wider than about 60 inches or taller than 48 inches may need a special configuration, structural review, or additional handling.
Glass selection also affects both the initial price and performance. Standard dual-pane insulating glass is generally the baseline; Low-E coatings, gas fills, laminated glass, or impact-resistant options can add roughly $75-$400 or more per unit, depending on dimensions and availability. Triple-pane glass, where offered for the specific configuration, may cost more and should be checked against the product’s current specifications.
Grilles, hardware finishes, custom colors, and factory-applied interior finishes can add another $25-$250 or more per window. Energy-performance ratings should be compared for the home’s climate and exposure rather than assumed from the series name. Get the exact size and glass package on every bid; otherwise, a low quote may be pricing a different window.
When Does Replacement Work Cost More Than New Construction?
Insert replacement keeps much of the existing frame and trim in place. If the frame is sound, the opening is square, and the new window fits, installation may take about two to four hours per unit and cost roughly $250-$500 in labor. It can limit finish work, but it may reduce glass area slightly and will not correct hidden damage around the original frame.
Full-frame replacement removes the existing window and frame down to the rough opening. This approach often takes four to eight labor hours per window, with installation labor around $400-$900 before repair work. It allows inspection of flashing and framing, but new trim, siding adjustments, or interior finishing can increase the total. A water-damaged sill or several feet of deteriorated framing may add $200-$1,000 or more.
New construction installation in an unfinished opening can be less disruptive to price than retrofitting a finished home, but it is usually part of a larger building project. Crew rates, access, number of windows, and finish requirements matter. Choose the installation method based on frame condition and water management, not on the lowest labor line alone.
What Do Regional Labor Rates Add to a Slider Window Quote?
Labor and overhead vary by market. As a rough comparison, installed prices in lower-cost rural and Midwestern markets may be 5%-15% below a national middle-range estimate. Large coastal metros and high-cost Western or Northeastern markets may run 15%-35% above it, especially when contractor availability is limited or finish labor is expensive.
For example, a straightforward installed window priced near $1,400 in a moderate-cost area could be quoted around $1,200-$1,350 in a lower-cost market or $1,600-$1,900 in an expensive metro. These are comparative estimates, not fixed regional price schedules; unit size and installation scope can outweigh geography.
Urban access, parking restrictions, upper-floor placement, scaffolding, and long delivery distances can add charges. Some contractors also have minimum service fees for a one-window project, making the per-window price higher than for a whole-house order. Compare at least three local, itemized estimates for the same dimensions and installation method.
Can Repairing an Andersen Slider Beat Replacing It?
Repair may be economical when the frame, glass, and sash are sound but the window sticks, leaks air, or has worn hardware. Cleaning and adjustment may cost $100-$250; a service visit with track or balance work can run $150-$400. Replacing a damaged lock or a small hardware component may add about $50-$200, depending on parts and labor.
Glass-only replacement can cost roughly $200-$600 or more per sash, based on size, glass type, and local service charges. It may make sense for a cracked pane when the rest of the assembly is in good condition. A failed insulated glass seal, frame rot, repeated water intrusion, or multiple damaged parts can make repair less attractive.
Before ordering parts, confirm the window’s identification information and whether the specific component is available. A contractor should inspect the sill, exterior cladding, and flashing if water is involved; replacing a sash will not solve a leak caused by failed installation. Compare repair costs with a written replacement quote when repairs approach one-third to one-half of a new installed unit.
Three Andersen 400 Slider Quotes for Common Projects
These examples show how dimensions and work scope can change a quote. They assume ordinary residential access, standard colors, and no major framing damage. Actual dealer pricing and local labor can differ.
| Project | Unit and labor assumptions | Estimated total | Approximate per-window price |
|---|---|---|---|
| One small insert replacement | 36-by-24-inch unit at $550; 3 labor hours at $100 per hour; $125 removal and trim | $975 | $975 |
| Four standard replacements | Four 48-by-36-inch units at $800 each; 4 hours per window at $95 per hour; $500 combined disposal and trim | $5,720 | $1,430 |
| Two large full-frame replacements | Two 60-by-48-inch units at $1,250 each; 7 hours per window at $110 per hour; $900 finish and repair allowance | $4,940 | $2,470 |
Project totals can change when a contractor prices a crew day, bundles delivery, or includes a warranty and finish package. Tax may be extra, and the repair allowance is not a guarantee that concealed damage will fit within the quoted amount.
Each estimate should specify whether labor is priced per window or as a project total, and whether the listed hours represent one worker or a crew. Use these examples to check quote logic, not as guaranteed prices for a specific home.
How to Lower the Price Without Sacrificing Fit
Keep the scope consistent when requesting bids. Provide the same rough opening dimensions, glass package, color, grille pattern, and replacement method to each contractor. Ask for separate prices for optional finishes and upgrades, and confirm whether the contractor has included disposal, flashing, insulation, trim, and cleanup.
Ordering several windows at once can reduce delivery and setup costs, though it does not guarantee a lower unit price. Scheduling during a contractor’s less busy period may improve availability, but weather and product lead times can limit timing. Avoid rushing an order until the measurements and specifications are verified; a misordered custom unit can create substantial delay and expense.
Choose standard dimensions and colors when they suit the opening, and avoid paying for grilles or specialty glass that do not meet a clear design or performance need. Do not save money by reusing a frame with rot or skipping proper flashing. The most reliable savings come from accurate specifications, sound existing framing, and comparable bids—not from removing essential installation steps.
Before accepting an estimate, check the warranty terms, start and completion dates, payment schedule, and responsibility for damage uncovered after removal. Confirm that the quoted product is an Andersen 400 Series gliding window and that its configuration is available for the measured opening. A detailed written scope reduces disputes over extras and helps explain why two quotes differ.
